Keroro Gunso Alternate Universes Wiki

The KuruToke Universe is a fan universe for Keroro Gunso. This universe includes different characters and designs for the previously existing characters in the anime/manga.

Lore

In the early days of Keron, Keronians were often 'region-locked' in the sense that some couldn't interact with others in their species. This produced various Keronian species specialized for different regions. These species are identified by colour, skin pattern, height, weight, and shape. In the current day on Keron, the species intermix regularly and hybrids are a common occurrence.

Keronian Details

Keronian species are based off of frogs and toads from real life. Keronian tadpoles don't have many identifiers early on in life, but the characteristics of their species eventually show up the closer they get to adulthood.

Horned Keronians

Horned Keronians have small, hornlike protrusions above their eyes. Their shoulders and backs have small bumps made of flesh that look like spikes. Individuals of this species are often green, brown, yellow, orange, or red with darker coloured spots. Some members of this species have a purple colour mutation, such as Garuru. Species inspired by Argentine horned frogs.

Notable species member(s): Giroro, Garuru, Putata, Pururu.

Gilded Keronians

Gilded Keronians are pure yellow-gold, with little to no patterning. Their skin is extremely smooth and can shimmer in the correct lighting. Touching one's skin will leave a yellowish residue. Species inspired by yellow dyer rainfrogs.

Notable species member(s): None.

Azure Keronians

Azure Keronians come in various shades of blue, with darker spots that vary in size. Azures are very agile compared to other Keronians and are often employed as assassins due to their ability to secrete a poisonous mucous from their skin. They use this mucous to create poison darts, hence the nickname of 'Poison Dart Keronians'. Species inspired by blue poison dart frogs.

Notable species member(s): Dororo, Taruru, Mekeke, Gyororo.

Chorus Keronians

Chorus Keronians have stripes in the corners of their eyes, typically darker in colour than their main skin tone. Chorus Keronians tend to be green, orange, or yellow. Chorus Keronians are very enthusiastic in resonances, often being the first ones to initiate it. They often have a call sign that varies from individual to individual, such as Keroro's classic "gero" or Kururu's distinctive laughter. However, this isn't exclusive to this species as members from other species also have these call signs (such as Putata). Species inspired by Pacific chorus frogs.

Notable species member(s): Keroro, Kururu, Tororo.

Frosted Keronians

Frosted Keronians tend to be white or grey, with markings of varying shape and colour. These Keronians have a heightened resistance to cold weather and dry air, tending to prefer to live in tundras. These Keronians also have a fairly low tolerance to heat, often having a hard time functioning closer to the equator. Species inspired by grey treefrogs.

Notable species member(s): Zoruru, Kagege.

Saddleback Keronians

Saddleback Keronians are often orange, with darker orange or almost red spots. Saddlebacks often have their darker colour on nearly 100% of their back, with some overlapping onto their shoulders and thighs. Their faces appear freckled. This species is relatively new, so not much is known about them. Species inspired by strawberry poison-dart frog (more specifically, Oophaga pumilio “Bastimentos”).

Notable species member(s): Tokeke.

Bioluminescent Keronians

Bioluminescent Keronians (nicknamed 'Glowsticks') are typically quite dark in skin-tone, with spots along their body that glow. The original members of this species have gone extinct, making their only living relatives hybrids. Hybrids of this species rarely develop bioluminescence; however, the dark skin-tone does carry over as well as developing spots later on in life that are lighter in colour than the rest of the body. Those who do not develop bioluminescence instead develop biofluorescence, where their patterning will appear to glow under blue light. Some members of this species are capable of controlling their bioluminescence, while others have their bioluminescence activate during combat or powering up special moves. The colour of their pattern determines the colour of the special move (for example, Tamama has bright purple spots. Therefore, his Tamama Impact glows a vibrant purple). Species and hybrids inspired by various poison dart frogs, as well as Godzilla.

Notable species hybrid(s): Tamama.

Life Cycle

Keronians lay 2 to 3 eggs on average, however, having more or less is also possible. The eggs are laid in a pool of water, which is constantly maintained until the tadpoles develop working limbs and lungs. Then, the pool can be drained for cleaning.

Eggs

Keronian eggs are around 6 inches in diameter. The shells are gelatinous and transparent, much like frog eggs on Earth.

Tadpoles

Keronian tadpoles can be brown, black, or a dark grey with a transparent tailfin. The body of these tadpoles are 6 inches long, 12 inches including the tail. These tadpoles feed on a puree of space fruits and vegetables. These tadpoles grow quite slowly.

Tadpoles (4 limbs)

When Keronian tadpoles reach this stage, they are ready to begin learning how to speak. These tadpoles become half of the size they will become as an adult, which can vary wildly depending on genetics. From this stage, their true colour begins to appear.

Young Keronian

At this stage, they are the equivalent of a froglet on Earth. This is where they begin to walk and begin going to school. Their lungs are fully developed at this stage, and are ready to come onto land. Their tails are short and barely assist with swimming.

Adult Keronian

Adult Keronians are sexually mature and no longer possess a fin. The white on their face recedes and the white on their belly connects to the bottom of their now shortened tail.

Cases of Neoteny

In rare cases, Keronians can retain their tail and larger face patch into maturity. This is called neoteny and is found in modern humans. Neoteny is when an animal (or alien, in this case) retains the features common in juveniles as an adult. Axolotlians are a prime example of this.
